I would like to show you this kind of emergency mouth releases for the first meters (the most risky) of an AT flight.
You don't lose any second to release and don't lose any control either with 2 hands on the basebar.
On the other side you have got a classic barrel release (straight pin).

The remote barrel

* L/A ratio (direct load/actuation effort): 16.8
* maximum permissible tow tension to remain within the 25 pound actuation requirement: 820lbs
* maximum load tested (also tested at all lower graduations): 300lbs

The "4 strings"

It is designed to be used in an emergency situation only and experiences significant wear when actuated under a heavy load.
Due to the stepping down and other reductions through the mechanical advantage, friction, and resistance of the mechanism, when subjected to a 240 pound tow tension in One Point configuration the load transmitted to the Trigger Line remains well under two pounds.
* L/A ratio (direct load/actuation effort): 60
* Minimum Tension : a direct force of about 30 pounds is required to effect a release.

Anything to keep the hands on the CB!!

I want a remote barrel, that looks simple enough...how much?

what happens when that pulley breaks with that thing in your mouth

I still can not understand, if you get to the point its gone real bad and you need to release, what you need both hands on the control bar for

The control of these things is weight shift....if you are locked out it means weight shift doesn't work any more

And if you're just approaching a lockout, taking a hand off the bar could be the very thing that puts you into a lockout.

The benefit is only limited by your imagination: you're on tow, when the tug gives you the rope just as you are clearing the tree line by a few meters- what you really want to do is ditch the rope and fly the glider- if you have to take hands off the control bar at such critical moments, you trade one for the other...

Please, if you don’t like the string in teeth idea that’s fine but to dismiss the notion that flying with one hand is no big deal in a critical situation is nonsense.

It’s easy to test, just fly fast and open and close you mouth, nothing much happens. Try the same experiment, but this time let go with one hand at the same time, a momentary loss of control.
Still nothing much happens of course, except if you find yourself experiencing some other momentary loss of control at the same time.

As for the comment…
‘what happens when that pulley breaks with that thing in your mouth’.

This is critical of course and a very valid point, certainly on top of my list of ‘things that might go wrong’ along with a buckled cross-tube a snapped hang loop and inexplicably poor denture cement.
The solution, fortunately, is a simple one. Only use the commonly found stuff that will take the weight of five fat people and not sh** rig equipment made from parts of an old toy, a box of matchers and a Parker ball point pen.

Looking at the video, the pilot can see the release in his peripheral vision. Several barrel release are made in various lengths. I chose the longer barrel release due to it is well in my peripheral vision. Yes, I have to let go with a hand to release, but I also have 2 barrel releasees so I can use either hand.

I'm not nocking the mouth release, but I won't to point out a couple things. The mouth release is not for me with a full face helmet and maybe someday going with a visor. I also surface tow as well as aero tow and even though I use different releases, I still use the same hand and the release lanyard is located only inches from each. Plus; I would not be able to yell, "damn this is going to hurt" if I got into a bad situation.

I've wondered about the same idea, but with a link knife..
looks good!
